Fig. 5From: Epidemiological investigation and drug resistance of Eimeria species in Korean chicken farmsComparison of intestinal lesion scores in field sample-infected chickens. Five-day-old ROSS 308 female chickens were orally infected with 3 × 104 sporulated oocysts of 9 different field samples (A–I). At day 7 post-infection, five chickens from each group were randomly selected for intestinal lesion scoring. Lesions scores range from 0–4, following the Johnson and Reid [24] scoring technique. * P < 0.05 indicates significant difference compared to untreated and infected group (PC). Results represent mean ± SE values. NC, negative control; PC, untreated and infected group as a positive control; A-I, farm samplesBack to article page
